When the'sc'rewl8 ismarawn, thepressing die 18can be readily removed'inwn obviousimanner. 1

Within the upper or movable die -I Ifl'fie M is also formed asemi-cylindrical seat l9 into which is fitted a correspondingly shapedpressing die 20. The upper pressing die 20 is also formed with a flatplate member 2| having semi-circular arms 22. The upper pressing die 20is freely mounted for rotation within its die holder Ill so that it can.readily assume different positions therein. However, the extent ofmovement of the pressing die 29 within its die holder I0 is limited bymeans of a screw 23 which passes through a slot 24in the top of the dieholder II].

On the opposite side of the stationary die holder 9 from that whichcarries the pivot pin ii, there are provided bearings 25 for a cam shaft26. As

clearly shown in Fig. III, the cam shaft 23 is connected at the rear ofthe machine to the crank arm 8 to which the previously described treadlemechanism is attached. The upper or movable die holder III is providedwith a laterally projecting portion 21 formed with an interior curvedcam surface as indicated at 28 in Fig. VIII. The surface 28 is so curvedthat with rotation of the cam shaft 25 the movable die holder I9 isforced A downward. Thus when the cam shaft is rotated in acounter-clockwisedirection, its cam 29 engages first the smoothly curvedcam surface 28, and then the sharply rounded extremity 39, causing themovable die holder Ill to be forced downward gradually against theresistance of the fabric to be pressed toward the stationary die holder9. 0n the other hand, when the cam shaft 25 is rotated in a clockwisedirection, an additional cam 53 on thecam shaft 25, clearly shown inFig. III, engages a block 64 on the projecting portion 21 of the movabledie holder l0, .causing the separation of .the die holders in an obviousmanner. Thus when the foot treadle 5 is pressed, the movabledie holderIll closes upon the stationary die holder 9, but with release ofpressure on the foot treadle 5, through the action of the spring 6, thecam shaft 29 is rotated in the opposite direction separating themovabledie holder II! from the stationary die holder 9.

Attached to. one of the depending arms I! of th lower pressing die 13,there is ashort link 3|. The 5 link 3| has at its upper end a slot 32 inwhich a pin 33 on the upper or movable die 20 is engaged. The link 3|causes the upper or movable die 20 to -be maintained in substantiallyParallel relation with the lower or stationary die I3, at the limit ofthe separating movement. When the movable die holder III is urgeddownward by rotation of the cam shaft 26, its die 20 will tend topartake of the same angular movement about the pivot pin II, but will befree to adjust itself to the fabric tobe pressed. Moreover, when themovable die holder lilris raised, its pressing die 20 will tend topartakev of the angular movement of the die holder, but willbe'restrained by action of. the link 3| and caused to: assume ahorizontalposition. While the slot 32 of the link 3| is shown to be ofelongated form, giving to the freely mounted die 29 a limited amount ofplay, it will be observed that at either limit of its movement the die29 will assume a. strictly parallel relation with the opposing die l3. r

. The lower or stationary die i3 presents a flat face 34 to thecompanion die. 0n the flat face .34 there are depressed areas 39 shapedto the form of collar points. At the edges between the depressed areas39 and the adjacent raised areas 36, there are right angular surfaces35, as shown Fig. VII. The upper or freely mounted die 20 is formed withcomplementary raised surfaces 1 3]; adapted to fit snugly upon thecorresponding depressed surfaces 39 of the lower die I 3. Thus the upperand lower dies 29 and I3 define between them a mold of the shape of twocollar points. Preferably this mold is further provided with a thin flatplate 38, which in the example shown is riveted to the depressedsurfaces 39 of the lower die, but which does not quite extend to theedges of the depressed surfaces 39 and hence forms recessed areas at themargins of the collar points when a collar fabric such as shown at 40 isinserted in the pressing machine. The recess'ed areas afford spaces forthe accommodation .of-the extra thickness of material, as indicated at,at the margins of the collar points, so

blade or form 3, shown in Fig. I, is inserted. The

blade or form 3 is shaped to the form of the collar 49, to be pressedand fits nicelyinto the depressed areas 39 of the lower die l3. As shownin Fig.I,the blade or form 3 is adjustably supported on a metal stripwhich has thereon a handle portion 43, and which is bent beneath thehandle portion and there joined to the guide member 4. As shown in Figs.I and V, the guide member 4 has a slotted end 44 through which bolts 45are inserted as a means of attaching the guide member 4 to the bladecarrying strip 42. By the above described connection, the verticalposition of the blade or form 3 may be adjusted to suit the convenienceof the operator. The guide member 4 slides withina'slot 45 at the baseof the pressing machine, and at the base of the machine there is alsoprovidedan extension,

41 having a similar aligned slot for the adequate support of the guidemember 4. The guide member 4 passes through the pressing machine to therear thereof and there terminates in an upturned end 43 which carries ashock absorbing spring 49. Attached to the upturned end 48 of the guidemember 4, there is a depending bracket 50 to which is connected one endof a spring 5|. The opposite end of the spring 5| is secured to theunderside of the inclined table 2, as indicated at 52. 1

, It will be apparent that when the blade or form 3 is moved into thepressing machine proper I, the spring 5| is placed under tension, sothat when the handle portion 43 is released the blade or form 3 will beautomatically retractedv to its original position. The shock absorbingspring 49 prevents any jarring of the machine when the blade or form 3is retracted.

As shown in Fig. H, the cam shaft 26 is provided at the front end ofthemachine with an additional cam 53. The cam 53 operates upon one endof a lever 54 pivoted at 55. The inner end of the lever 54 engages a pin56 which is affixed to a movable cutter 51. The inner end of the lever54 is attached to the end of a spring 59, the other end of which issecured to the base of the pressing machine. The cutter 51, in theexample shown, is of substantially rectangular outline and is slidablevertically within a correspondingly shaped groove, clearly indicated at59 in Fig. VI. At the top of the cutter 51 there are two projections 60which have sharp flat cutting edges 6I which penetrate through openings52 in the face 34 of the bottom die l3. When a collar such as shown at40 is inserted in the pressing machine, and the movable die I9 isoperated to perform the pressing operation, rotation- Gilatrthemmshaftllthronghtheactionof the lslr-allpoauseszupward invariantof the cutter llvmthecmltincedgm ii otthe'proiectinns munceaaed to thefabric and to animate These cuts or perforations are dh'eetlons of thedot-and-dash lineman: and v.

VII,flemlir'shapes and rigidly confines the mpaint durincthe pressingoperation; and theme-min: die 20. having, as before stated, a contourcomplementary to the. recess sewn; the wali surfaces 36, is receivableinto said recess.

The operation of the pressing machine will be apparent from the abovedescription. It will be especially noted, however, that the mutuallyopposing pressing dies I3, assume a parallel relation to each otherbothwhen closed and when fully separated. Accordingly, the insertion andremoval of the form I which carries the fabric is facilitated, and thefabric is smoothly pressed. In operation it is not necessary that theform 3 remain between the pressing elements of the machine during thepressing operation. The operator may first apply the collar fabric tothe form I, then push the form to a position between the upper and lowerdies ",20. Then the operator may release his grip on the handle 43,permitting the form to be automatically retracted through action of thespring 5|. Subsequently, the operator actuates the foot treadle 5,causing the freely mounted die 2| to move downward to efiect thepressing of the fabric. At the same time the operator may use hishandsto apply a new article to the form 3. Finally the operator removesthe pressed article and repeats the operation on the second article.

While I have described in some details one particular example of amachine embodying my invention, it will be apparent that many changesmay be made in the form of the various instrumentalities specificallyshown and described herein, without departing from the spirit of theinvention as defined in the annexed claims.
